CAR-COUPLING.

SPECIFICATION forming part of Letters Patent Nd.580,487, dated April 13,1897. Application filed November 19, 1896. Serial No- 6l2,'775. (Nomodel.)

To all whom, it may concern:

Be it known that We, ASIA M. HARDIN and WILLARD B. PENDLEION, citizensof the United States, residing at Lodiburg, in the county ofBreckinridge and State of Kentucky, have invented certain new and usefulImprovements in Automatic Oar-Couplings; and we do declare the followingto be, a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

ur invention has relation to improvements in automatic car-couplings;and the object is to provide a simple, durable, and reliable device ofthis kind.

To this end the novelty consists in the construction, combination, andarrangement of the same, as will be hereinafter more fully described,and particularly pointed out in the claim.

In the accompanying drawings the same letters and figures of referenceindicate the same parts of the invention.

Figure 1 is a perspective View of our invention. Fig. 2 is alongitudinal section of the same in position for coupling, and Fig. 3 isa similar view with the parts in position for uncoupling.

1 represents the draw-head, formed with longitudinal slot 2 in its topand a similar though smaller slot 3 in its bottom. A longitudinal recessa is formed in the top of the forward end of said draw-head. A T-shapedcoupling-pin 4 is pivoted on a rod 5 so as to swing freely in the upperslot 2, its lower arm 6 engaging the lower slot 3 in the bottom of thedraw-head. The upper integral arm I) of said coupling-pin 4c is adaptedto engage the longitudinal recess a in the drawliead and limit theupward movement of said pin when the cars come together. '7 representsan integral eye on the shank 8 of said coupling-pin, and it is connectedby a short chain 9 to the depending arm 10 of a transverse shaft 12,sliding laterallyin bearings 13 13 on the end of the car. The outer endof this shaft terminates in a hand-lever 14, which, when it is hangingdownward, allows the coupling to rest by gravity in the position shownin Fig. 2, and

while in this position, if the link on the opposite car be inserted inthe draw-head, it pushes the arm 6 backward and upward, the link ridingunder it until the link has passed the end of the arm, which then fallsby gravity through the open end of the link back to its first position,thereby locking the link in the draw-head.

To release the link and uncouple the cars, the lever 1a is raised, whichraises the arm 10 and by means of the chain 9 lifts the coupling-pin toa horizontal position and releases the link. If it is desired to retainit in this position, the lever 14 is forced inwardly a short distanceuntil it rests on the inclined face 15 of the block 16, which holds thecoupling-pin in an elevated position, the arm I) of the coupling-pinresting snugly in the recess a in the draw-head to secure the sameagainst accidental displacement.

To release the pin, so that the cars will conple automatically, thelever 14 is pulled outwardly from the block 16 and allowed to drop down.This releases the coupling-pin, and it is left free to act by gravitywhen a link is inserted in the draw-head.

Although we have specifically described the construction and relativearrangement of the several elements of our invention we do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of our invention without departing fromthe spirit thereof.

Having thus fully described our invention, what we claim as new anduseful, and desire to secure by Letters Patent of the United States, is-

The draw-head 1, formed with the alined longitudinal slots 2 and 3, theformer provided with a continuous inclined recess a, the coupling-pin L,pivoted on the transverse rod 5, and provided with the integral arm (3,projecting into the slot 3, and the eye 7, in the integral shank S, incombination with the horizontal transverse sliding shaft 12, formed withthe integral hand-lever 14, and the integral longitudinal depending arm10, the solid bearings l3 13 in which said shaft is mounted, saidbearings so arranged with reference to the lever 14 and the arm 10 as tolimit the longitudinal movement of said shaft in either In testimonywhereof We hereunto affix our direction, the chain 9, connecting theouter signatures in presence of two Witnesses. end of the arm 10, withthe eye '7 of the coup- ASIA M.
